What the Validator Checks

The validator parses your JSON-LD, including arrays and @graph blocks, and flags invalid JSON and missing @context or @type before you publish.

What It Doesn't Check

It doesn't check property names or values against Schema.org or Google's rich result requirements. Use Google's Rich Results Test for eligibility and the Schema.org validator for vocabulary errors.
